Title: Electronic clock or clock radio with an alarm signal of differing loudness level
Inventor: HOFFMANN HARALD DR
IPC: G04G13/02
Filed: 1982-08-13
Abstract: The subject-matter of the invention is an arrangement for generating differing loudness levels for the emission of an alarm tone by an electronically controlled clock or a clock radio. Connected in parallel with a piezoelectric element (8) which serves as sound transducer is an inductor (9) whose self-induction voltage is controlled by differing switch-on times of an electronic switch (7) that is connected to the control electronics (2) of the clock or clock radio. In this arrangement, the base of the electronic switch (7) is connected via a resistor (70) to a pulse-width control circuit (20). The loudness level of the alarm emitted by the piezoelectric element rises with a rise in the self-induction voltage output to the piezoelectric element (8) by the inductor (9). <IMAGE>
Patent DE-3232096-A1 (DE)
Title: Inlet chute of a drying oven for fine-grained wet material to be dried
Inventor: HARTMANN HEINZ LEOPOLD DIPL IN
IPC: F26B25/00
Filed: 1982-08-28
Abstract: The inlet chute is to be constructed so as to eliminate the causes of lump formation in the material to be dried on the chute as well as the heavy wear. This aim is achieved by an auxiliary device for heating and maintaining a constant temperature at an elevated temperature level which lies in the steam temperature range and which is expediently situated at 350-390 DEG C. When such an inlet chute is kept at this elevated operating temperature, it is ensured that the surface water on the coal sludge particles evaporates suddenly when the stream of coal sludge reaches the inlet chute. The steam which thus constantly arises leads to a spatial separation between the arriving sludge granules and the inlet chute, so that wear is greatly reduced as a result. The steam layer which is constantly renewed between the coal sludge and the inlet chute thus acts like a lubricant for the material to be dried which is introduced.

Filed: 1982-10-01
Abstract: In a machining centre with a toolholder unit displaceable in the horizontal plane in the Y- and Z-direction and with a rotary worktable displaceable on a column in the vertical X-direction, the column is pivotable about a vertical pivot axis. In one embodiment, the rotary worktable can be rotated directly about a horizontal axis of rotation so that five axes of movement (three translational axes and two rotational axes) result. In a second embodiment, the rotary worktable is constructed so as to be rotatable about a second axis on the horizontal axis of rotation, this second axis of rotation intersecting the horizontal axis of rotation at right angles. Six axes of movement (three translational axes and three rotational axes) are obtained. Machining of the workpiece is possible from all sides and at any angle with simple numerical control.

Title: Process for producing a panel from rigid foam with channels to receive pipelines of a panel heating system
IPC: F24D3/14
Filed: 1982-12-29
Abstract: The invention relates to the production of a rigid-foam panel of this kind, in particular with a heat-reflective layer, in particular metal coating, arranged on the panel side having the channels, the foam being foamed in a closed mould and remaining there until curing in the mould which has mould ribs arranged and formed on one mould side corresponding to the channels to be formed. To improve said production such that, while increasing the dimensional stability of the panel, in particular a simplification of the production of panels having arcuate channels can be achieved, it is proposed first of all to form channels (3), corresponding to the particular channel profile and channel path required, in particular by thermoforming, in a stiff plastic sheet (1) which can be formed without cutting to form relatively stable structures, simultaneously to form inwardly projecting pipeline-retainer detent lugs (5) arranged at a distance one behind the other on the channel side walls in the longitudinal extent of the channels (3), and to foam the foam (2) on the reverse side of the plastic sheet permanently formed in this manner. <IMAGE>

Title: Arrangement for automatic electrolyte circulation
Inventor: LAUNHARDT HELMUT
IPC: H01M2/38
Filed: 1983-04-19
Abstract: An accumulator cell, especially for traction batteries of vehicles, has, in a known manner, electrodes of different polarity and intermediately-connected separating walls in a trough-shaped housing with an electrolyte supply space arranged above the electrodes. In order to bring about very simple automatic circulation of the electrolyte, it is intended to provide at least one isolating wall (14), which divides the electrolyte supply space (12) into at least two sub-spaces (12a, 12b), connected to the electrodes (6, 7), and which allows electrolyte passover essentially only in one direction. Furthermore, the sub-spaces (12a, 12b) are intended to be connected to one another via through-passage spaces which run essentially along the electrodes and separating walls, in order to compensate for electrolyte levels of different height which form during movement of the electrolyte. In this case, the isolating wall (14) is expediently intended to have a through-passage opening (19) provided with a non-return valve device (20, 21), and through-passage openings (23) are also intended to be provided on the retaining webs (10) which are arranged in the sludge space (11), in order to make an electrolyte flow possible. <IMAGE>

Title: Safety device for the blade fastening on comminuting machines
Inventor: BAUER HERMANN
IPC: B02C18/18
Filed: 1983-05-06
Abstract: This safety device serves for the fastening of cutting or chopping blades, which are held in a respective, outward-tapering wedge groove of a tool carrier of a comminuting machine, by a centrifugal wedge which is under prestress. The rear side of the centrifugal wedge and the floor surface of the wedge groove form sliding surfaces which form a wedge angle, the vertex of which is directed towards the periphery of the tool carrier and effects self-locking. Moreover a support wedge is loosely inserted between the sliding surfaces. The centrifugal wedge is thus moved slightly outwards owing to centrifugal force, so that a secure support of the centrifugal wedges is achieved without additional elastic pressure means.
